Re: Ultrasound probe cleaning and disinfection

[Sony SO]

Dear All,

We are using this wipes ie the Tristel wipes http://www.tristel.com/, it is a manual reprocessing system. When compare to Trophon, which it is an automatic process and with validating test to ensure the probe has completed the high level disinfection process.

We using the Tristel wipes in those dept with infrequent use of USG probes. For dept with frequent use of USG probes, we recommend to use the Trpohon.

Hi Fiona

I have not seen this particular system in Australia, but the questions I would be asking are:

1. Is the disinfectant licensed with TGA as an instrument-grade disinfectant (ie high level disinfectant)? If not, you cannot proceed as these devices require high level disinfection with a TGA approved disinfectant.

2. Has the manufacturer / sponsor of the disinfectant provided evidence of materials compatibility with the specific TV probe you use? This preferably would be advice from the probe manufacturer to say the disinfectant is safe to use with the probe.

Since it is unlikely current Australian guidelines will reference a product that was not on the Australian market when the guidelines were written, this is the process I would follow.

If both of the above are provided to your satisfaction, form an IC perspective I would be happy to permit the use of the product in a specific situation.

Cheers

Hi All,

I have been asked to review a new cleaning and disinfection system for reprocessing transvaginal ultrasound probes especially those used in IVF related pregnancies where chemical residues are a high concern.
The system consists of three separate pre-packaged wipes (a cleaner, a disinfectant and a rinse wipe) which I believe is currently used in he UK. The active ingredient in the disinfectant wipe is chlorine dioxide in aqueous solution.

Has anyone got any experience with this type of system that they would be willing to share with me?

Kind Regards,
